The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 is the scheme drawing according to the tower crane load connecting device of the embodiment of the invention 1.As shown in Figure 1, this tower crane load connecting device comprises: upright pedestal 1 is used to be connected to an outside vertical plane; First bearing 2 is arranged on the facade of upright pedestal 1; Second bearing 4 is arranged on the facade of upright pedestal 1, is positioned at the top of first bearing 2, and spaced apart with first bearing 2; Bent axle attaching parts 3 comprises: vertical shaft portion 31 be installed in rotation on first bearing 2 and second bearing 4, and crank portion 32, one ends are connected in vertical shaft portion 31, and from vertical shaft portion 31 horizontal-extendings, the other end forms suspended end.
In practical operation, upright pedestal 1 can fix on the wall or other object on so that play fixation to whole tower crane load connecting device.Can articulate corresponding load on the crank portion 32.
Because bent axle attaching parts 3 is fixed on the upright pedestal 1 by first bearing 2 and second bearing, 4 these two strong points, thereby bent axle attaching parts 3 provides stable supporting role can for crank portion 32, even when being subjected to axis with the bent axle attaching parts and having the power of angle, bent axle attaching parts 3 can not twist yet.
Further, first bearing 2 and second bearing 4 can be arranged in parallel.Like this, can under the certain situation of the material of first bearing 2 and second bearing 4, provide bigger bearing force; Perhaps, under the situation of the required specified bearing force that provides, save the material of bearing.
Further, first bearing 2 and second bearing 4 are separately positioned on the bottom and the top of vertical shaft portion 31.Like this, can under the certain situation of the material of first bearing 2 and second bearing 4, provide bigger bearing force; Perhaps, under the situation of the required specified bearing force that provides, save the material of bearing.
Here, the lower surface of second bearing 4 has groove, and the upper end of vertical shaft portion 31 is installed in this groove, so that form a fixed connection between second bearing 4 and vertical shaft portion 31.
Principle of work to the tower crane load connecting device of present embodiment is described in detail below.
Down, articulate the load that remains to be fixed on the crank portion 32 in working order, upright pedestal 1 is fixed on the metope.As shown in Figure 3, be connected with the bottom of upright pedestal 1, on the position of first bearing 2, form first fulcrum, so that bent axle attaching parts 3 is supported by first bearing 2.Equally, be connected with the top of upright pedestal 1, on the position of second bearing 4, formed second fulcrum, so that bent axle attaching parts 3 is further supported by second bearing 4.
Because the effect of load, one end of bent axle attaching parts 3 may be subjected to the effect of load force F1 and F2, wherein F2 can be the power that the axis direction with bent axle attaching parts 3 neutral axial regions 31 forms an angle, F1 can with the parallel power of axis direction of bent axle attaching parts 3 neutral axial regions 31.Owing to there be first fulcrum and second fulcrum that supports bent axle attaching parts 3 simultaneously, thereby bent axle attaching parts 3 can not twist, the parts of load attaching parts carry load can run-off the straight or deformation yet, therefore, guaranteed that tower crane load connecting device can stably accept load, prolonged the service life of self.
Can assemble the tower crane load connecting device in the present embodiment in the following manner, it comprises:
S11 is installed on the fixed block 21 in first bearing 2 and second bearing 4 on the upright pedestal 1.
S12 links to each other compact heap 22 usefulness screws with the screw of fixed block 21, keep compact heap to be in relaxed state this moment.
S13 passes hole between compact heap 22 and the fixed block 21 with the vertical shaft portion 31 in the bent axle attaching parts 3, and inserts in the groove of second bearing 4, and guarantees that bent axle attaching parts 3 is inserted into the bottom of this groove, and here, groove is arranged on the lower surface of second bearing 4.After adjusting the direction of bent axle attaching parts 3, tighten the screw that links to each other with compact heap, just can apply load force F in crank portion 32 this moment.
Fig. 2 is the scheme drawing according to the tower crane load connecting device of the embodiment of the invention 2.The difference of tower crane load connecting device shown in Figure 2 and tower crane load connecting device shown in Figure 1 is: the annexation of second bearing 4 and bent axle attaching parts 3.In the present embodiment, the connection mode of second bearing 4 and bent axle attaching parts 3 can adopt the connection mode that is similar to first bearing 2 and bent axle attaching parts 3 among the embodiment 1.
Concrete, second bearing 4 comprises the fixed block 41 that is fixedly installed on the upright pedestal 1 and the vertical shaft portion 31 in the bent axle attaching parts 3 is pressed abd fixed on compact heap 42 on the fixed block 41, wherein, form the hole of matching between fixed block 41 and the compact heap 42 with the outside face of bent axle attaching parts 3.In the present embodiment, fixed block 41 can be as shown in Figure 2 with the direction of compact heap 42, and fixed block 41 all can be connected with upright pedestal 1 with compact heap 42.Here, the direction of fixed block 41 and compact heap 42 can also and Fig. 2 in fixed block 21 consistent with the direction of compact heap 22, that is, fixed block 41 is installed on the upright pedestal 1, is connected by screw between fixed block 41 and the compact heap 42.
In the foregoing description 1 and 2, second bearing 4 can form as a whole with bent axle attaching parts 3.In addition, second bearing 4 is welding with the connection mode of upright pedestal 1 or is threaded.
In the present invention, tower crane load connecting device adopts two attachment points to fix and the bent axle attaching parts, even thereby when being subjected to axis with the bent axle attaching parts and having the power of angle, the bent axle attaching parts can not rotate, the parts of load connecting device carry load can run-off the straight or deformation yet, therefore, guaranteed that tower crane load connecting device can stably accept load, prolonged the service life of self.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
